Fundsters may yet see one of their own in the U.S. Senate come 2013. In an interview with Reuters' Ross Kerber, MFS [see profile] chairman emeritus Bob Pozen fanned the flames of rumor about a possible Senate run without giving a firm answer one way or the other.

"I'm not running for Senate unless the Democratic Party asks me to, if they want someone who is socially liberal and fiscally disciplined," Pozen told Reuters, adding that the Dems "shouldn't choose" him if they want someone more confrontational and less centrist.

The Senate seat Pozen is eyeing is the Massachusetts one formerly held by Ted Kennedy (D) and now held by Scott Brown (R). Brown is up for reelection next year.

This isn't the first time Pozen (who once led Fidelity's FMR investment adviser arm) has been publicly discussed as a possible challenger to Brown. In December the Boston Herald and the Washington Post both previously reported that Pozen was in such talks (see see The MFWire, 1/3/2011).

Pozen isn't a political neophyte. Reuters describes him as "a steady Democratic donor," he served as an economic adviser to then-Massachusetts governor Mitt Romney, and he held a post on President George W. Bush's Social Security reform commission.&nbsp
